Abstract (en)

[origin: EP2653686A1] Provided is an exhaust-pipe injection system capable of accurately monitoring a lowered injection pressure generated in a fuel line due to exhaust pipe injection and appropriately perform feedback control for the exhaust injection amount. The exhaust-pipe injection system includes: an exhaust pipe injector 16 that injects fuel to an exhaust pipe of an internal combustion engine; a supply pump 12 that sends a fuel to the exhaust pipe injector 16 via a fuel line 24; a pressure compensating means 28 provided in the vicinity of the exhaust pipe injector 16 of the fuel line 24; a fuel pressure sensor 29 provided in the fuel line 24 in an upstream side from the pressure compensating means 28; and an injection control means 27 that adjusts an injection amount of the exhaust pipe injector 16 based on a monitoring value of the fuel pressure sensor 29.
